Merge PDF
Combine multiple PDF files into a single document, in the order you choose.
Processed in your browser — files never uploaded
Merge PDF lets you combine two or more PDF files into one document without installing anything. Drag your files in, drag to reorder them, and download a single merged PDF.
Everything runs locally in your browser, so your files are never uploaded to a server. That means it works even with sensitive contracts, reports, or personal documents.
Frequently asked questions
Is there a limit to how many PDFs I can merge?
No hard limit. Since merging happens in your browser, the practical limit is your device's memory rather than a server quota.
Can I change the order of the pages before merging?
Yes. After adding your files, drag them into the order you want the final document to follow before merging.
Do my files get uploaded to TAMPDF's servers?
No. Merge PDF processes files entirely in your browser using client-side technology, so your documents never leave your device.
Will merging affect the quality of my PDFs?
No. Pages are combined as-is with no re-compression, so text, images, and formatting stay exactly as they were in the originals.
